The agreement was delayed late last month over what Ban called "procedural issues" and not over any fundamental differences in the agreement. It had been circulated to eight countries: Congo, the Republic of Congo, Rwanda, Uganda, Burundi, South Africa, Angola and Tanzania.

The peace deal is an effort at a large-scale political framework to end violence in Congo. Separate talks are taking place in Uganda between the rebel group known as M23 and Congolese officials.

Jean Baptiste Rudaseswa, a lawyer for M23, has said the plan could further destabilize Congo.
